Patent DE-2260583-A1 (DE)
Title: Pressurised plastic container - with thin side wall, concavo-convex lower wall and peripheral rim forming double thickness
Inventor: JONES ELWYN
IPC: B65D1/02
Filed: 1972-12-11
Abstract: Thin, flexible pressurised container of thermoplastic material, esp. for gaseous drinks, has an annular side wall section formed under differential pressure, with an upper neck for pouring the drink, and a bottom, formed under differential pressure, which has a concavo-convex lower wall and a continuous peripheral rim forming a double thickness lower wall. A part of this rim has an external of the part of the side wall section internal diameter of the part of the side wall section into which it penetrates, so that it can be inserted by friction. The welding material, situated radially at a distance and axially facing the concavo-convex wall and interposed between the parts of the rim and the side wall section, around the lower wall, adheres strongly to this lower wall at the side wall section. The container resists relatively high internal pressure, and is cheap to mfr. esp. as the wall is relatively thin.

Title: Hot gas regulator valve - esp. for continuous combustion engines has cooling tube arrangement
Inventor: VOGELSANG GUSTAV
IPC: F02G1/05
Filed: 1973-06-16
Abstract: Hot gas regulator valve is constructed as a hollow unit with an internal cooling tube and cooling means activated by the valves opening action.

Title: Coin case with two polystyrene covers - with self locking pin closures, and cavities for sepd. coins
Inventor: PFEIFER MICHAEL
IPC: A45C11/24
Filed: 1973-07-12
Abstract: Coin case consists of 2 cooperating cover parts and a fitting inlay with coin cavity/cavities fitting the shape of a coin. The 2 cover parts have self-locking closures. Pref. the closuree each consist of a spindle on one cover part and a blind bore in the other, with equal dias. The cover parts are of polystyrene, and the spindle is sharp-edged. Both cover parts may be transparent. Each cavity is an opening through the inlay and stepped at the periphery; the further opening part fits, in dia. and height, the dia. of a given coin with negative tolerance, and the dia. of the smaller opening part is smaller than the coin dia. to an extent that the resulting shoulder reliably takes up the loading by the coin and the resulting stress in the cover part. Contact of the coins in the case is prevented.

Title: High voltage cable for high loads and low field strength - uses rippled impregnated insulating tape of increased thickness and width
Inventor: KUHN ERNST DR
IPC: H01B9/06
Filed: 1973-08-14
Abstract: The cable is used for current at 110-350 KV and it has a large diameter conductor and with an insulation of oil impregnated papers tape kept under oil or gas pressure.

Patent DE-2346074-A1 (DE)
Title: Bottle with sealing cap - has inner sealing lip on cap uncovering dispensing opening on release
Inventor: FISTER DIRK
IPC: B65D47/24
Filed: 1973-09-13
Abstract: The bottle is particularly for use with such commodities as household cleaning materials, where a large opening is provided for initial filling and a smaller one for subsequent dispensing. The end face of the cap has a sealing lip working against the inside of the bottleneck, and which seals the bottle when the cap is in place. When the cap is loosened and thus moved for a set distance in the axial direction, this lip merely uncovers the smaller opening for dispensing. The cap can be narrowed at a point clear of the end face, working in conjunction with a bead on the outside of the bottleneck. The narrowed portion can slide over the bead on initial fitting, but it is difficult or impossible to remove it the other way subsequently.
Patent DE-2347981-A1 (DE)
Title: Lavatory flushing with booster water pressure - allows necessary water volume to be substantially reduced
Inventor: STRAKATA JOSEF
IPC: E03D3/10
Filed: 1973-09-24
Abstract: Lavatory flushing with booster pressure of reduced water consumption where the outlet speed of the flush water in the bowl is raised by increased pressure, low resistance water passage and the efficient shape of the flush stream. The necessary water volume for flushing of solid and fluid bowl content can then be reduced to a fraction of the former consumption such that the apparatus consists of a flusher and a blower orifice, both of which have short water paths without sudden directional and cross-sectional changes. The flusher has two separate operating elements which automatically return to their output position by means of rotary springs.
Patent DE-2354918-A1 (DE)
Title: Decorative plastic foil with wood-grained surface - with pore-like surface-curvatures produced during heat-moulding process
Inventor: HOERDLER GISBERT
IPC: B44C1/24
Filed: 1973-11-02
Abstract: Thermoplastic foil is made into a profiled from a planar foil pattern, the surface of the foil being embossed at the same time. The visible surface of the mould-profile possesses a wood-type surface structure. While the decorative element is made, as usual, from a planar pattern by thermal moulding, pore-like curvatures are simultaneously produced in the foil, the depth and distribution of these curvatures lending a wood-like surface structure to the decorative element. This method, while simple, ensures that the embossed parts, which determine the embossed image, are not obliterated, either wholly or partly, during the heat-moulding operation.

The plates are rectangular, so that there is formed an uninterrupted ring enclosed by the outer curved face of the trought. At the outer end of each arm is a roller which locates in an open trough shaped rim around the main trough so that the divider unit is supported by rollers. At the extreme end, beyond the roller, each arm is hooked, and carries a locking screw to lock the arm against the rim of the secondary trough.

Title: Arrangement for fixing images in photocopier - provides even cover of fixing liquid and satisfactory damp roller contact
Inventor: EPPE RUDOLF DIPL PHYS DR
IPC: G03G15/20
Filed: 1974-02-21
Abstract: The apparatus fixes images consisting of powder electrostatically attracted to a selenium layer. The reverse side of the copy carrier is in contact with a damp roller. A copy carrier of moisture penetratable material has a corona discharge arrangement near the roller, which dips into a fixing fluid.

Title: Screw type vehicle jack - has lug engaging with weld seam pivoting during lifting movement
Inventor: HAFNER FRANZ
IPC: B66F3/12
Filed: 1974-06-22
Abstract: The jack has a supporting arm pivoting on a transverse axis on a column under the action of a crank-operated screwed spindle working in a nut and carried in bearings in arm and column, to raise and lower the coachwork. At the free end of the arm is a lug with a recess in it by which it engages with a weld seam on the underside of the coachwork. The lug (18) pivots on the arm (14) on an axis (46) parallel to the arm pivot axis (16) as the arm itself pivots, under the action of a link (30) attached between arm and column (10). Thus during the pivoting movement of the arm the weld seam (22) remains in approximately the same position in relation to the lug.
